My first success has already happened! While my husband was deployed to Iraq last year, he bought me a new wedding band. He mis-heard my ring size (7.5) and bought me a 7. It was a bit tight when he first got home, and then I gained some weight after he got home and it got TIGHT-- Like I'm talking I could barely get it on and off, and I was going to go get it fixed.
WELL-- Since I have started this, my fingers have shrunk and my ring fits!! It's still a bit tight, but I can get it on and off without sticking my hand under cold water-- and I don't feel like it is cutting off my circulation!!!!!!!
